DOOR AND WINDOW SCREEN Application filed April 26, 1929.

This invention relates to screen construction, an object being toprovide a screen frame whose structure is such as to securely clamp thescreen fabric to the frame and to stretch and maintain the fabric inproperly taut condition, the construction being adapted for either dooror window screens.

Another object of the invention is the provision of novel means forhingedly :nounting the screen so that it may be removed and replacedfrom the inside of a building, together with means for locking thescreen in closed position, whereby the screen may be swung laterallywhen it is tlesired to open a window or door, or may be securely held inclosed position.

With the above and other objects in view, the invention -furtherincludes the following novel features anddetails of construction, to

be hereinafter more fully described, illustrated in the accompanyingdrawings and pointed out in the appended claim.

In the drawings Figure 1 is an elevation illustrating the invention.

Figure 2 is an enlarged sectional view through the screen.

Figure 8 is an enlarged fragmentary sectional view on the line 3-3 ofFigure 1.

Figure 4 is an enlarged fragmentary elevation partly broken away andshowing the means for actuating the screen lock.

Figure 5 is an enlarged fragmentary sectional view on the line 5-5 ofFigure 1.

Figure 6 is an enlarged fragmentary section on the line 66 of Figure 1.

Figure 7 is a detail perspective view of one of the hinges.

Figure 8 is a like view of the attaching plate for the hinge.

Referring to the drawings in detail wherein like characters of referencedenote corresponding parts, the reference character 10 indicates awindow frame which is shown for the purpose of illustrating theinvention. It will be apparent however that the screen may be used as adoor screen and it is not the purpose of the present application tolimit the invention in this particular.

The screen frame is of novel construction Serial No. 358,399}.

and comprises asection 11 which is substantially L shaped in crosssection as shown in Figure 2 of the drawings. The frame also includes asection 12 which is adapted to be secured within the L-shaped section 11as by screws or fastening devices 13. The sections 11 and 12 may be madeof either metal or wood.

The meeting faces of the sections 11 and 12 may be corrugated orprovided with complemental ribs and depressions 14 and 15 re spectively,and provide clamping faces between which is clamped the edges of thescreen fabric 16. The fabric is thus securely attached to the frame, andin addition, the securing means acts to properlystretch and hold thefabric taut.

In order to hang the screen, the invention provides hinges of novelconstruction. These hinges include plates 17 and 18 which are pivotallyconnected as shown at 19. The plates 17 are adapted to be secured to thescreen frame, while the plates 18 are provided with spaced elongatedslots 20 which re ceive staples 21 carried by an attaching plate 2'2.This last mentioned plate is secured within the window frame as shown inFigure 6 of the drawings with the staples extending through the slots 20of the hinge plate 18.

A retaining pin 28 is then passed through the D staples so that thehinge plate is securely attached. The pins 28 may be attached to thewindow frame by means of chains 24 and. pins 25.

The side of the frame remote from the hinges is longitudinally groovedas shown at 26 and this groove is closed by a removably attached plate27. Slidable within the groove 26 are aligned rods 28 whose inner endsare spaced apart as shown in Figure i of the drawings and whose outerends extend beyond the ends of the frame and are removably receivedwithin suitable sockets 29 provided in the window frame. The inner endsof the rods 28 are yieldingly forced apart by means of a spring 30 andin order to retract the rods so as to release the frame, these innerends are engaged by the ends of operating levers 31. These leversarepreferably shaped as shown in Figure 4 of the drawings and are pivotallyconnected as shown at 32 so that by pressing the outer ends of thelevers inward or toward one another, the rods 28 may be retracted andthe 5 screen frame released from the window frame.

The invention is susceptible of 'various changes in its form,proportions and m-i-nor details of constructionand the right is hereinreserved to make such changes as properly fall within the scope of theappended claim.

Having described the invention what is claimed is A look for a hingedlymounted member comprising aligned longitudinally disposed lockingrodsadapted to be mounted for longitudinally sliding movement insaidmemher and having their inner ends spaced apart and their outerendsadaptedfor engagement with keepers,:a pairyof pivotal 'ly connectedcrossed arms having one of their ends .operatively secured to the innerendsofthe rods, with the inner .ends of the'rods eX- tending through.said arms, wher'eby the rods may be moved relatively outward, and aspring positioned between and having its opposite ends engaged over..the ends of the rods to yieldingly force the latter outward.

In" testimony whereof we aflix our signatures.
